Karrie Webb ended up in a tie for second place, but her final round at the US$2.75-million CN Canadian Women's Open was one of missed opportunities.

Webb started the day six shots off the pace set by Suzann Pettersen and roared out of the gates at the Priddis Greens Golf and Country Club to pull within three strokes after only five holes, but she just couldn't keep it going.

Her undoing, ultimately, was leaving birdie putts short on the seventh and ninth holes. Had she drained them, Webb would have pulled within one stroke of Pettersen for the lead, and set the stage for an exciting chase to the finish.

Instead, she was left leaving to answer why those putts didn't fall.

"Do you want to ask the man upstairs why they didn't go in? I don't know," she said, showing the competitive fire that's pulled her second on the LPGA's all-time money list with more than US$15 million in career earnings.

"I tried 100% to make the putt and they didn't go in.

"I can't tell you why they didn't go in. I wish I knew."

Webb shot a 2-under 69 to finish in the five-way tie for second at minus-10.

Webb, who won the event when it was held at Priddis Greens 10 years ago, enjoyed the fan's love this year.

"I really appreciated the crowds this week. They treated me like a defending champion, so that was fun," she said.

"I didn't think I'd get that close so soon on the front nine, but it just wasn't meant to be."
